FINGERPRINT RECOGNITION SYSTEM

This project is to design a fingerprint recognition system for security purposes. It will
also explore and suggest some solution to the improvement to the existing fingerprint system.
Security system that uses a pin code or access card can be easily misused or mishandled. A pin
code can be cracked using some hacker software while an access card can easily be stolen or
misplaced. Thus, these security methods are very vulnerable to hackers and criminals. Instead, a
fingerprint is unique to every person and due to the fact that no two people have the same
fingerprint pattern, it makes the fingerprint a very good resource in a security system.
The aim of this project is to focus on the concept and methodology of the fingerprint
recognition system. By grasping the concept and method of the fingerprint recognition flow, a
prototype is developed that will compare an input fingerprint with its predefined template. The
system should be able to compare and decide if the input fingerprint is the same as the
predefined template.
The output of the first stage is a preprocessing stage. There are two stages involved in
preprocessing which is the image enhancement and image skeletonization. Fourier transfonn and
histogram equalization is utilized to enhance the low quality image to a better image so that the
feature extraction process will run smoothly.
The second stage of the project is to define the orientation, ROI extraction and minutia
extraction. The matching sequence and the angle orientation problem were resolved.
